The ZTZ99 is the most higher level primary battle tank (MBT) associated with the PLA. The ZTZ99 provides a substantial improvement in firepower, flexibility, and security compared to older Chinese-made tanks. A few of the ZTZ 99 ' s technologies happen used to update the less costly ZTZ96 MBT. The hull of the ZTZ99 is quite much like that of the T-72, it is about one metre much longer. The turret and hull are of all-welded metal armour construction. The front arc regarding the turret can be added with a layer of composite armour, or arrow-shaped spaced add-on armour modules. The armour package is of modular design, allowing damaged sections to be replaced or improvements installed throughout service life
